WC = 35.74 + 0.6215(20) − 35.75(15^0.16) + 0.4275(20)(15^0.16) = 6.2°F.

WC = 35.74 + 0 − 35.75(25^0.16) + 0 = -24°F. Frostbite in 10–30 minutes.
The NWS wind chill formula is: WC = 35.74 + 0.6215T − 35.75V^0.16 + 0.4275TV^0.16, where T is air temperature (°F) and V is wind speed (mph). It requires wind above 3 mph and temp below 50°F.
| Air Temp | 10 mph Wind | 20 mph Wind | 30 mph Wind |
|---|---|---|---|
| 30°F | 21°F | 17°F | 14°F |
| 10°F | -4°F | -9°F | -12°F |
| -10°F | -28°F | -35°F | -39°F |
Frostbite can occur in 30 minutes at wind chill of -10°F, in 10 minutes at -25°F, and in under 5 minutes below -35°F. Exposed skin (ears, nose, fingers) is most vulnerable.
No. Wind chill only affects warm-blooded organisms. Objects cool to the ambient air temperature regardless of wind. However, wind makes them reach that temperature faster. Pipes freeze based on air temp, not wind chill.
Mount Washington recorded a wind chill of -103°F in January 2004 (actual temp -44°F with 87 mph winds). In populated areas, the Upper Midwest regularly sees -40 to -60°F wind chills in polar vortex events.
